Question

PLZ HELP ASAPPP I just need with 1 and 2 this is my very last assignment! Thank you guys for all your help this yr!

Answer 1

1. a = 32.96 m∠B = 21° b = 12.74

2. x = 24.99

Explanation:

1. Use the law of sines:

a/sin 112 = 26/sin 47

a = 26 sin 112/sin 47

a = 32.96

m∠B = 180 - 47 - 112 = 21°

b/sin 21 = 26/sin 47

b = 26 sin 21/sin 47

b = 12.74

2. Use the law of cosines

`x^(2) = 17^(2) + 11^(2) - 2(17)(11) cos 125`

= 289 + 121 - 374 cos 125

= 624.5175....

x =
`√(624.5175...)`

= 24.99
